Title: Safety tire and take-apart wheel construction
Inventor: WEEKS JAMES B
IPC: B60B25/22
Filed: 1988-03-25
Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE           A take-apart wheel rim and disc assembly for use in a safety tire and wheel assembly which includes a pneumatic tubeless tire.  The wheel includes an inboard rim part, a wheel mounting disc having an outer marginal flange telescoped into and secured to the inboard rim part, the disc flange having an outer surface protruding axially outboard beyond and clear of the inboard rim part.   An outboard rim part telescopically received from an axially outboard direction over the disc flange, an O-ring seal disposed between the disc and opposing surfaces of the inboard and outboard rim parts, and a clamp ring for axially clamping the outboard and inboard rim parts together with the O-ring captured in compression between the disc and the opposing surfaces of the rim parts to seal against air leakage.  The disc has an air bleed vent structure outboard of the O-ring and normally sealed from the tire cavity by the O-ring.  The clamp ring and associated fasteners engage and exert clamping stress on the outboard rim part over a range of relative movement therebetween in the axial direction relative to the inboard rim part which is sufficient to permit loss of sealing pressure at the O-ring prior to loss of clamping engagement to thereby permit air leakage past the O-ring through the air bleed vent structure to atmosphere within the range of relative movement.

Granted: 1995-08-08
Abstract: A fibrous substrate having a first coefficient of thermal expansion and having porous characteristics is formed from discrete elements, such as carbon fibers, having anisotropic properties. A matrix formed from a refractory material encases the discrete elements and has a second coefficient of thermal expansion different from the first coefficient. The matrix has minimal chemical or mechanical bonding to the discrete elements to provide for a displacement of the matrix relative to the substrate with mechanical shock or changes in temperature. The matrix includes a first element having refractory properties and selected from the group consisting of hafnium, zirconium, tantalum, tungsten and molybdenum and also includes a second element bound to the first element. The matrix is preferably formed by providing a mixture of a firstgas containing the refractory element and a second gas containing the second element and by introducing the gases into a chamber containing the substrate. The gases are introduced into the chamber at an elevated temperature and with a pressure pulsating at a particular rate between first and second pressure limits to obtain the deposition of the refractory material on the discrete elements. The gases are periodically exhausted from the chamber and fresh gases are introduced into the chamber. The matrix may consist of first and second layers respectively having hafnium (e.g. hafnium carbide) and zirconium (e.g. zirconium carbide) as the refractory materials. These layers define pores with the substrate and further define an external surface. A layer of rhenium may cover the matrix in the pores and in the external surface.

Abstract: ABSTRACT            SPACE HEATING AND VENTILATION SYSTEMS FOR BUILDINGS         A heating and ventilation unit has a ceramic heat wheel rotatable within a housing between first and second plenums 3, 4 through which fresh and stale air, respectively, are forced to pass in a hot air ventilation system.  The heat wheel is made of cordierite material such as is used in catalytic conversion systems for automobiles.  It is formed with non-communicating and axially extending parallel pores having a pore density of 62 pores per sq. cm.  As it rotates the heat wheel transfers to the fresh air both the heat generated by a gas burner in the second plenum, and also low grate heat contained in the stale air.  The burner is housed within a combustion housing by means of which the combustion gases are confined to a generally D-shaped area of the heat wheel.  The combustion housing is spaced from the walls of the second plenum to form an annular passage through which unheated stale air passes to cool the walls of the second plenum and purge any combustion gases from the pores of the heat wheel entering the first plenum. Humidification of the fresh air may be achieved by water sprayed onto the upstream surface of the heat wheel in the first plenum.
